Bump!
Just found out that there's a leak photos from SSB for 3DS/Wii U that it might be possible that, C. Falcon and Wario will be coming back, but i don't know if they actually fixed Wario's dumb move as flammableking said. I found out that there may be total of 39 characters in the picture i found out, but i can't tell if it's real or fake, but i don't think it's real though. If it is real, then allright.

I saw Falco may be coming back, but it's not yet confirmed. At least someone has to come back. XP
Another thing is that i want to tell, there may be some slots for characters left, but i don't know which one will be though. Read this thread, people!
